When you click and drag on a value in the inspector panel, if your mouaw reaches the edge of the display while you are dragging (ie if you are dragging the value to the right), the value jumps up dramatically.

eg dragging position:Value starts at 0Start dragging to the rightValue is at say 150Hit the edge of screen > Value jumps to 1500

This makes it very difficult when trying to fitness positioning/cropping etc and has been the absolute worst bug trying to conform sequences with lots of photos / repos required.
